Other claims from this paper (11)
- Intervention effect Nonnodulated soybean plants grown with nitrate accumulated more dry matter than plants given nitrate and Rhizobium (N+R).
- Intervention effect At pod filling under natural light, plants given nitrate and Rhizobium (N+R) had higher dry matter than nonnodulated N plants.
- Intervention effect Rhizobium-inoculated (R) plants had the lowest dry matter accumulation.
- Intervention effect Rhizobium-inoculated (R) plants showed the earliest senescence.
- Association Nodule size, rather than nodule number, was a good indicator of nitrogen fixing activity in soybean.
- Intervention effect Nitrate suppressed nodule size and specific activity in soybean.
- Intervention effect Rhizobium-inoculated (R) soybean plants had the lowest seed yield.
- Intervention effect Nitrate-grown (N) soybean plants had the highest seed yield.
- Intervention effect Plants given nitrate and Rhizobium (N+R) had the highest pod number per plant.
- Intervention effect Rhizobium-inoculated (R) soybean plants had almost the lowest yield components.
- Recommendation Adequate combined nitrogen supply in addition to nodule-fixed nitrogen is suggested as necessary for high soybean yield.
